Title

[MU047A], Letter from Francis Robbins Upton to Elijah Wood Upton, April 4th, 1880

Editor's Notes

discusses his trip after leaving his family; "Profs. Brackett and YOun were here yesterday and made a number of tests on the machine we are using which showed quite well. The light is very slowly progressing; a little slower than I should wish. It is hard to make the lamps we want though we can made very good ones. We have placed our hopes very high for we can make lamps with a few hours life which are extremely economical and there seems to be now reason why we cannot make them last many hours in time. I know the light is a commercial success as we have it but not in every case sufficiently so to make it take the place of gas."
